Bacteria and archaea differ in____ a.whether they have a nucleus.. b.the makeup of their cell walls.. c.size.. d.whether they have a cell wall. The answer is b.the makeup of their cell. Both bacteria (which belong to the group of Prokaryotes) and Archaea have no nuclei but have cell walls. Those are groups of unicellular organisms. But, they differ in the makeup of their cell walls. Archaea have cell walls made of uncommon lipids while bacteria have cell walls made of peptidoglycan. Comments.

Archaea Domain Little is currently known about the major characteristics of these organisms. We do know that they are thermophilic and have been found in hot springs and obsidian pools. Archaea Phylogeny. Archaea are interesting organisms in that they have genes that are similar to both bacteria and eukaryotes. Phylogenetically speaking, archaea and bacteria are thought to have developed separately from a common ancestor. Eukaryotes are believed to have branched off from archaeans millions of years later. This suggests that archaeans are more closely related to eukayotes than bacteria.

Marine life Introduction (from Wikipedia). The Archaea constitute a domain or kingdom of single-celled microorganisms. These microbes are prokaryotes, meaning that they have no cell nucleus or any other membrane-bound organelles in their cells. Bacteria constitute a large domain of prokaryotic microorganisms.

Bacteria Members of these two prokaryotic domains are as different from one another as they are from eukaryotic cells. Prokaryotic cells (i.e., Bacteria and Archaea) are fundamentally different from the eukaryotic cells that constitute other forms of life. Prokaryotic cells are defined by a much simpler design than is found in eukaryotic cells.

Archaea In the past Archaea were classified as an unusual group of bacteria and named archaebacteria, but since the Archaea have an independent evolutionary history and manifest numerous differences in their biochemistry from other forms of life, they are now classified as a separate domain in the three-domain system.n the past Archaea were classified as an unusual group of bacteria and named archaebacteria, but since the Archaea have an independent evolutionary history and manifest numerous differences in their biochemistry from other forms of life, they are now classified as a separate domain in the three-domain system.

Biology Unit 9 Microbiology And Biodiversity Some texts still refer to the Archaea kingdom as the Archaebacteria kingdom; however, this term has recently been abandoned because they are not bacteria; they are archaea. What makes these two groups of organisms so different is their genetic make-up, primarily the gene sequences of ribosomal RNA (rRNA).

Antibiotics Seek Out Bacterial Cells Bacteria and human cells also differ in the structure of their cell membranes and the machinery they use to build proteins or copy DNA. Some antibiotics dissolve the membrane of just bacterial cells. Others affect protein-building or DNA-copying machinery that is specific to bacteria.acteria and human cells also differ in the structure of their cell membranes and the machinery they use to build proteins or copy DNA.

Archaea Domain Archaea. Archaea are a group of microscopic organisms that were discovered in the early 1970s. Like bacteria, they are single-celled prokaryotes. Archaeans were originally thought to be bacteria until DNA analysis showed that they are different organisms.rchaea are interesting organisms in that they have genes that are similar to both bacteria and eukaryotes. Phylogenetically speaking, archaea and bacteria are thought to have developed separately from a common ancestor. Eukaryotes are believed to have branched off from archaeans millions of years later.

What are the differences between archaebacteria and eubacteria? Archaeabacteria is a kingdom in the domain Archaea, and Eubacteria is a kingdom in the domain Bacteria. Both kingdoms contain bacteria that are prokaryotic, unicellular, and a … utotrophs or heterotrophs. However, Arechaeabacteria have cell walls without peptidoglycan which is the opposite from Eubacteria.

The members of both Archaea and Bacteria have several similarities. For one, they are all prokaryotes. This means, they are all one-celled and are absent of a true nucleus.

Flagella: Definition, Structure & Functions The flagella of domains bacteria and archaea are different. They still move the cell, but they do so by rotating, rather than by bending from the inside like eukaryotic flagella. The flagella of archaeans are superficially similar to those of bacteria. However, there are key differences.ilia are similar to flagella in structure and function, but a cilium is shorter and moves differently. A ciliated cell usually has hundreds or thousands of cilia, which move in unison like little oars.

- In the archaea, there is no nucleus, but many genes behave like those in higher organisms. Archaea are thought to have a common ancestor with bacteria, but billions of years ago the third domain, eukaryotes, broke off from archaea, eventually developing into plants, animals and us.esearchers say that the heat and geochemical conditions in volcanic regions may be similar to conditions that existed on the young, water-covered, cooling Earth. Almost like a creature from science fiction, the volcanic microbe is different from the two other basic branches of life: bacteria and eukaryotes.

Archaea Other aspects of archaeal biochemistry are unique, such as their reliance on ether lipids in their cell membranes. Archaea use more energy sources than eukaryotes: these range from organic compounds, such as sugars, to ammonia, metal ions or even hydrogen gas. Bacteria and eukaryotes have membranes composed mainly of glycerol-ester lipids, whereas archaea have membranes composed of glycerol-ether lipids. 2  The difference is the type of bond that joins the lipids to the glycerol moiety; the two types are shown in yellow in the figure at the right.

Formulas for Circle Area and Circumference: Simple as Pie Formulas for Circle Area and Circumference: Simple as Pie. In this video from Cyberchase, Bianca and her friend team up to sell pies. Bianca learns that pie-pan sizes are the measured diameter of the pan, but that there is a mathematical relationship between the diameter of the pan and the circumference of the pan. In the accompanying classroom activity, students calculate the circumference of a variety of wheels.

Are eukarya more closely related to bacteria or archaea? · just now. Report Abuse. The correct answer-based on the most recent research-is that they are not closely related to any of these groups. All three domains of life (bacteria, archaea, and eukaryotes) are separate, and with the most current knowledge it is impossible to say which two shared a common ancestor.Eukaryotes and archaea share some characteristics, but so to bacteria and archaea.Based on older research, eukaryotes seem to share more with archaea, and that might be the answer your teacher wants to hear, but the most recent insights cannot tell to which of these two eukaryotes are most closely related.Source(s): http://www.ucmp.berkeley.edu/alllife/thr...ased on older research, eukaryotes seem to share more with archaea, and that might be the answer your teacher wants to hear, but the most recent insights cannot tell to which of these two eukaryotes are most closely related.

Difference between Archaea and Bacteria Prokaryotes microorganisms can be further classified into three domains: eukarya, bacteria and archaea. This can become a bit confusing as these two are similar in looks and can often be confused based on look alone, though these are different from each other in many ways.

Examples of Archaebacteria With Their Scientific Name & Classification Archaebacteria are organisms that are actually very different biochemically and genetically from other bacteria. Hence, archaebacteria is an outdated term, and they are now classified in the Archaea domain. Classifications within this domain are unofficial due to debates over the descendancy of microbes.ence, archaebacteria is an outdated term, and they are now classified in the Archaea domain.
